Restrict model dropdown to only show text-to-text supported models

[raftaar1191]

Currently, the model selection dropdown on the Plugin Check Namer tool displays all available models, including those that do not support text-to-text generation. This can cause confusion because some of the listed models cannot be used for the intended functionality of generating names/descriptions.

The dropdown should ideally be filtered to show only models that support text-to-text capabilities.

Page where the issue occurs

/wp-admin/tools.php?page=plugin-check-namer

Current Behavior

• The model dropdown lists all models returned by the provider API.
• Models that do not support text-to-text generation are also included.
• Selecting unsupported models may lead to failed or invalid responses.

Expected Behavior

• The dropdown should only display models that support text-to-text generation.
• Non-compatible models (e.g., embeddings, vision-only, or other incompatible model types) should be filtered out before populating the dropdown.

Steps to Reproduce

1. Go to WP Admin → Tools → Plugin Check Namer.
2. Open the model selection dropdown.
3. Observe that the dropdown lists all models, including ones that do not support text-to-text tasks.

Suggested Improvement

Filter the models returned from the provider API based on their supported capabilities and only include models that support text-to-text generation.

For example:

• Exclude embedding models
• Exclude vision-only models
• Include only models with text generation capability

Additional Context

This filtering would improve usability and prevent users from selecting incompatible models for the Plugin Check naming feature.
